and use of the appliances described in these instructions. It
is recommended that the installer become familiar with
these standards and practices, local codes, and any special
requirements of the authority having jurisdiction.
An attached 24 VDC strobe at 110, 75, 15, or 15/75 candela
(cd) is also included with the speaker. Although they are
assembled into a unit, the strobe and speaker are electri-
cally independent and require separate power sources.
The speakers can operate at any one of four input power
levels at either of two input voltages. The system voltage
and sound power levels are selected at the time of installa-

Installation - For Strobe Placement See NFPA 72,
Chapter 6
NOTE: Installation procedure must comply with all appli-
cable local codes and any special requirements of
the authority having jurisdiction.
Electrical
All wiring must be installed in compliance with the National Electrical Code and all applicable local codes as well
as any special requirements of the authority having jurisdiction, using the proper wire size. This also includes all
applicable NFPA Standards, ANSI/UL 1480, and NEC 760.
1. Connect the speaker and strobe as shown in Figure 2.
Keep in mind that even though the speaker and strobe
are a single mechanical unit, they are electrically independent - the strobe must be connected to a DC supply
and the speaker to a 25V
or 70.7 V
rms
amplifier.

2. See Figure 2. The speaker is equipped with five posts
and an associated plug with red and black wires. The
center post is COM (common) while the others are labeled 2W, 1/4W, 1/2W, and 1W, respectively.
The installer selects any one of four input power levels
by installing the plug onto COM and the appropriate
power post. When connecting this plug, make sure the
black wire is connected to the COM post and the red
wire to the numbered post. Otherwise, permanent
speaker damage could result.
CAUTION
If the power option plug is not plugged into one of the option positions, the speaker will not sound and there will be
no trouble indication at the panel. Always make sure that
the individual speakers are tested after installation per
NFPA regulations.
Mounting
A. General
Both slotted head and Phillips head screws are supplied
with the speaker/strobe. Use the slotted head screw to
mount the device or combination of devices on the electrical box. Use the phillips head screws for attaching accessories to the speaker.

amplifiers, permanent damage

can result if the speaker is improperly connected. Therefore, be sure to use the COM and 25 terminals when a 25
V
amplifier is being used. Similarly, use the COM and

70.7 terminals if a 70.7 V
amplifier is in the system.

B. Surface Wall Mount
See Figure 3. Attach the speaker/strobe to a standard 4inch electrical box, using the two 8-32 X 1-7/16" slotted
screws provided. Fill the remaining screws with the

screws. Wires connecting the device to the control
panel must be broken at the device terminal connection to ensure electrical supervision.
